Raiders head coach Jon Gruden, possibly flushed with a last minute come-from-behind 7-6 victory over the San Diego Chargers, was arrested approximately three hours after Sunday's game for drunk driving.

According to Officer Steve Creel, spokesman for the Dublin office of the California Highway patrol, Gruden, 35, was spotted at about 7 p.m. Sunday as he drove a 1997 black Mercedes south on Santa Rita Road near West Las Positas Boulevard in Pleasanton.

"He was exceeding the posted 35-mph speed limit and straddling the line," Creel said, adding that he was stopped when he made a turn onto Valley Avenue.

"The officers determined that he had been drinking," Creel said, "gave him a field sobriety test and placed him under arrest."

Gruden requested a blood test which was administered at the Valley Care Medical Center in Pleasanton. Officials said it usually takes between 10 days and two weeks to determine the blood alcohol content.

After spending about three hours in Santa Rita Jail in Dublin, Gruden posted bail and is due to appear in Alameda County Superior Court in Pleasanton on Nov. 9.

Reached at his home Monday night, Gruden told the Contra Costa Times he wants to wait "to see if justice prevails."

"I'm confident it will," he said.

Gruden, former Philadelphia Eagles offensive coordinator and currently the youngest head coach in the NFL, signed a multiyear contract with the Raiders in January. He inherited a team that had a dismal 4-12 season last year. So far this year, the team is 4-2, tied for second place with Kansas City in the AFC West, two games behind the 6-0 Denver Broncos.&lt;
